Integrated Calling (also known as HD Voice Calling) is a feature of The Verizon Message Plus App which allows mobile devices such as Tablets and Smartwatches to connect to the Verizon Mobile Network to transfer data. Integrated Calling also allows these mobile devices to use the subcriber's main Verizon number to make and receive phone calls on these same mobile devices; as a Stand Alone Device (without being attached to a phone). I am requesting, as other has, to fix this ASAP! Or you will lose a customer! Enough said!
